2010 Chevrolet Silverado 1500 LS 4dr Crew Cab 5.8 ft. SB (4.8L 8cyl 4A)
Purchased a new 2010 Silverado and after 200 miles the interior noise became unbearable on the highway. Sounds like the rear passenger door of the crew cab is not closed. The door is closed, but the cab vents behind the rear seats are allowing for loud road noise. Wind noise can be heard though the weather strilling around the doors at hiway speed. Went back to the GM dealership to complain, and even though they admited that my vehicle is louder than most vehicles, I was told that "they all sound like that". I find this an unacceptable answer. The dealership offered to Duct Tape over the cab vents, but this would make closing the doors difficult.
Good power from the 4.8l engine, traction control works well. Smooth riding vehicle.
Pay more attention to the quality of the vehicle. Cheap interior and terrible quality control. How they can mass produce a vehicle with such obvious flaws is a perfect example of how GM went into financial trouble. Show some pride in your product & fix all the wind and road noise issues so you feel like you are driving a solid, quality vehicle.
Just wanted to let you know that we also have the same noise issue in our truck as well.
We have the 2010 CS LT Crew Cab.
One thing that we found was that by changing the tires, it made a huge difference.
We had 285/70/17/s on the truck, and switched to 265/70/17/s and it is a lot quieter.
Still a little noise, but not near as much.
Yes, it does sound like the rear passenger window is either cracked open a little or the door is ajar, but the instrument panel didn't indicate such.
Once we identified the issue and located the noise, it doesn't bother us anymore.
We just got over it basically.
We can still hold a conversation in the vehicle without any issues.
